HOLLYWOOD ? Disney-Pixar's charming tale about the last robot left on planet Earth and his quest for love, "Wall-E," won the Oscars best animated feature film prize here Sunday.

The groundbreaking film pipped "Kung-Fu Panda" and "Bolt" for the prize, the fourth time Disney-Pixar has won the category since it was created in 2001.

Directed by Andrew Stanton, "Wall-E" tells the story of a robot whose job is to gather garbage left behind on Earth after humans abandon the planet.

The movie is widely considered to be a milestone in animated movie-making, winning praise for its stunning artwork depicting a desolate, rubbish-strewn Earth in the distant future.

The film is notable for being almost entirely free of dialogue during the opening 40 minutes, instead following the character of "Wall-E" around as he methodically sorts out and stacks up garbage.

The silent movie-style opening was inspired by the films of Charlie Chaplin. The drama of the film revolves around the arrival on the planet of another robot, EVE, who captures WALL-E's heart.
